如何结束在c ++中显示菜单的重复？

因此，我是C ++的新手。我有此代码，需要输入要查看的内容。代码中发生的事情是，当我选择一个输入（例如1）时，它将显示Peripherals列表。当我在“外围设备列表”中输入5时，它将返回主菜单。在主菜单中，如果输入了4，则主菜单正在循环播放或一次又一次地重复。如果我输入4，则需要退出它或结束。

 #include <iostream>

    using namespace std;

    int main()
    {
        int choice;
        int pick;
        char view;

        cout << "\n" << endl;
        cout << "\t \t -------------------------------------------------------------------" << endl;
        cout << "\t \t \t \t \t WELCOME TO SHOPPING SPREE" << endl;
        cout << "\t \t -------------------------------------------------------------------" << endl;
    //MENU
    do {
        cout << "What type of items would you like to view?" << endl;
        cout << " [1] Peripherals" << endl;
        cout << " [2] Mobile Phones" << endl;
        cout << " [3] Consoles" << endl;
        cout << " [4] Exit" << endl;
        cout << "Enter your choice: ";
        cin >> choice;


        if (choice == 1) {
            cout << "\n";
            cout << "What peripherals would you like to purchase?" << endl;
            cout << "[1] HyperX Alloy FPS PRO" << endl;
            cout << "[2] SteelSeries APEX PRO" << endl;
            cout << "[3] Razer Kraken X" << endl;
            cout << "[4] AORUS K7" << endl;
            cout << "[5] BACK TO MENU" << endl;
            cout << "Enter your choice: ";
            cin >> pick;
        }
        else if (choice == 2) {
            cout << "\n";
            cout << "What mobile phones would you like to purchase?" << endl;
            cout << "[1] Xiaomi Mi Mix 3" << endl;
            cout << "[2] Oppo Reno" << endl;
            cout << "[3] Realme 5" << endl;
            cout << "[4] Samsung Galaxy 10" << endl;

            cout << "Enter your choice: ";
            cin >> pick;
        }
        else if (choice == 3) {
            cout << "\n";
            cout << "What consoles would you like to purchase?" << endl;
            cout << "[1] PlayStation 5" << endl;
            cout << "[2] Nintendo Switch" << endl;
            cout << "[3] PlayStation 4" << endl;
            cout << "[4] XBOX S" << endl;
            cout << "[5] BACK TO MENU" << endl;
            cout << "Enter your choice: ";
            cin >> pick;

    }
    while (pick == 5);
    }
